A Basic Plan Information Document (BPID) is a document that provides essential information about an energy plan. It includes key details such as contract terms, pricing, fees, and any additional conditions associated with the plan.

A benefit period, also known as a fixed benefit period, refers to the set time during which a customer receives particular benefits under an energy plan. For example, a discounted rate or promotion may be applicable for the first 12 months of the contract. If the contract is terminated during the benefit period, an exit fee may apply.

A conditional discount is applied to your energy bill based on certain conditions or agreements. For instance, if you pay your bill in full and on time, you may be eligible for a pay-on-time discount. 

A consumption charge, also called a usage charge, is the cost of the electricity or gas you consume. It is calculated based on the amount of energy used during a billing period. 

The contract term, also known as a fixed term or contract length, refers to the duration of an energy contract. It specifies the start and end dates of the agreement, commonly either a year or two years.

A type of tariff that charges customers different rates for electricity depending on when it is being used. The different times are often called peak, shoulder, and off-peak. 

The amount of electricity or gas you use. 

A usage charge, also called a variable charge or consumption charge, represents the cost of the electricity or gas you consume. It is calculated based on the amount of energy used during a billing period. 

A variable rate, also known as a market rate, refers to a pricing structure in which the price per unit of electricity or gas can change over time.
